The Helmet Diamond Glass 4D is a tempered glass screen protector specifically designed for the Samsung Galaxy S10. Its 4D construction ensures that the glass extends beyond the flat surface to cover the curved edges of the display, providing a seamless fit in black. This protective layer acts as a shield against daily wear and tear by resisting scratches, dust, and shocks from accidental impacts. While it is engineered to maintain the original touch sensitivity of your screen for smooth navigation, please note that this specific model does not support the ultrasonic fingerprint sensor. It is an ideal choice for users who prioritize comprehensive physical protection for their front display over biometric functionality.
